The main national roads
that supported early modern Japan

The Tokaido and Nakasendo were established by the Edo Shogunate, which ruled Japan from the 17th to 19th centuries, as the main roads in early modern Japan. The Shogunate developed stone-paved slopes and numerous post towns. For the purposes of maintaining public order and defense, numerous checkpoints and large castles were also built along the roads. Additionally, both roads were used for the shogunate's unique system of alternate attendance and for diplomatic missions to Japan, making them indispensable when discussing the political system of the Edo Shogunate. In addition, since both roads were used by many people regardless of social status, they also greatly supported economic, cultural and artistic activities. Cultural properties related to the Tokaido and Nakasendo provide a multifaceted understanding of early modern Japan's politics, economy, culture and arts.
